This OB1 Clear Multi-Surface Construction Sealant & Adhesive is designed for trade professionals and DIY enthusiasts undertaking construction, maintenance, and repair tasks. Its key benefit is providing a strong, waterproof, and weatherproof bond across a wide range of materials for both interior and exterior applications. A potential consideration is its clear finish, which while versatile, may not be suitable for all aesthetic requirements where a coloured sealant is preferred.

Once fully cured, most paints can be applied over OB1 Clear Sealant. It's advisable to test compatibility with your chosen paint first.
Unopened tubes typically have a shelf life of 12-18 months when stored correctly in a cool, dry place. Check the packaging for specific expiry dates.
You will need a standard cartridge applicator gun for dispensing the sealant from the 290ml tube.
Uncured sealant can be wiped away with a damp cloth. For cured sealant, mechanical removal might be necessary.
Ensure the cartridge is properly loaded into the applicator gun and the release trigger is engaged. Check that the nozzle tip has been cut open sufficiently.
Verify that the surface was clean, dry, and free from dust, grease, or contaminants before application. Ensure the product has not passed its expiry date.
Practice with the applicator gun on a scrap surface to achieve a consistent pressure and movement. Ensure the nozzle cut is appropriate for the joint width.
This may indicate insufficient ventilation or application in very high humidity. Ensure adequate airflow and avoid application in extreme weather conditions. Allow more time for curing.
